DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0027] like Figure 1 As shown, the electric mop provided in this embodiment includes a mop head and a mop rod 1. A motor 2 and a transmission shaft 3 driven by the motor 2 are arranged in the mop rod 1. The power output end of the transmission shaft 3 is connected to a steering assembly 4 arranged at the connection between the mop head and the mop rod 1. The steering assembly 4 is rotationally connected to the rotating cleaning structure of the mop head, and converts the power of the transmission shaft 3 along the axial direction of the mop rod 1 into a rotational power along the length direction of the mop head.

[0028] In a specific embodiment, the power source can be taken from a household socket power supply, or can be a battery pack arranged in the mop rod 1. When the power source is taken from a household socket power supply, it can be connected to the motor 2 in the mop rod 1 through wires.

[0029] In a specific implementation, in order to meet different needs of customers, one or more gear structures can be provided between the motor 2 and the transmission shaft 3, so that the motor 2 and the transmission shaft 3 rotate at different speeds.

[0030] When the electric mop starts working, the control switch is turned on to provide power to the motor 2, the output end of the motor 2 starts to rotate, and the transmission shaft 3 also starts to rotate under the drive of the motor 2. The steering assembly 4 turns the power of the transmission shaft 3 rotating along the axis of the mop rod 1 into a rotational power along the length direction of the mop head. After the power is converted, it finally causes the cleaning component to rotate, completing the electric cleaning.

[0031] In a specific embodiment, a rotating rod is provided inside the cleaning component of the mop head to drive the cleaning component to rotate. The rotating rod can be directly or indirectly connected to the steering assembly 4 for rotation. The steering assembly 4 directly or indirectly converts the power of the transmission shaft 3 rotating along the axis of the mop rod 1 into the rotation power of the rotating rod along the length direction of the mop head, thereby driving the cleaning component to rotate.

[0032] Since the utility model uses a motor 2 and a steering assembly 4 connected to the mop rod 1, specifically, the steering assembly 4 turns the power of the transmission shaft 3 connected to the output end of the motor 2 along the axial direction of the mop rod 1 into a rotational power along the length direction of the mop head, so that the motor 2 is not arranged in the mop head of the electric mop, so that the mop head of the electric mop can be directly immersed in water for cleaning.

[0033] In a preferred embodiment, the rotary cleaning structure includes a rotary drive rod 5 along the length direction of the mop head and a cleaning assembly driven to rotate thereby, and the rotary drive rod 5 is rotatably connected to the steering assembly 4 .

[0034] When the electric mop starts to work, the control switch is turned on to provide power to the motor 2, the output end of the motor 2 starts to rotate, and the transmission shaft 3 also starts to rotate under the drive of the motor 2. The steering assembly 4 turns the power of the transmission shaft 3 rotating along the axis of the mop rod 1 into the rotational power of the rotating drive rod 5 along the length direction of the mop head, and then the rotating drive rod 5 drives the cleaning component to rotate, so that the cleaning component cleans the ground.

[0035] The arrangement of the rotating mop rod 1 is not only convenient to install, but also common in the market and low in cost.

[0036] like Figure 2-5 As shown, in a specific embodiment, the electric mop also includes a guide assembly, two first traction ropes 6 and a first pulling structure provided on the mop rod 1, the cleaning assembly includes a first cleaning assembly 701 and a second cleaning assembly 702 which are symmetrical along the axis of the mop rod 1, and are respectively sleeved on the two parts into which the rotating drive rod 5 is divided by the steering assembly 4, the guide assembly is located between the mop head and the mop rod 1, one end of the two first traction ropes 6 are connected to the first pulling structure, and the other ends are respectively connected to the opposite sides of the two cleaning assemblies after changing the extension direction through the guide assembly, and when the first pulling structure pulls the two first traction ropes 6, the two cleaning assemblies are compressed in the opposite directions along the two ends of the mop head.

[0037] The guide assembly includes a cross bar 8 which is parallel to the rotating drive rod 5 and fixedly connected to the mop rod 1, first steering components 901 respectively provided at the connection between the cross bar 8 and the mop rod 1, and second steering components 902 respectively provided at both ends of the cross bar 8. The two first traction ropes 6 pass through the first steering component 901 and the second steering component 902 in sequence. The two first steering components 901 turn the two first traction ropes 6 from the direction of the mop rod 1 to the direction along the two ends of the cross bar 8, and the two second steering components 902 further turn the two first traction ropes 6 to the middle direction along the cross bar 8.

[0038] In a specific implementation, the first steering component 901 is a steering column or a steering elbow or a bearing, and the second steering component 902 is a steering column or a steering elbow or a bearing.

[0039] When the electric mop starts cleaning, the operation process is the same as above and will not be repeated here; when the electric mop needs to squeeze water, the two first traction ropes 6 are pulled through the first pulling structure set in the mop rod 1. After the two first traction ropes 6 are guided by the guide assembly, the two cleaning components are finally pulled back and compressed along the two ends of the mop head. Specifically, in this embodiment, the two first traction ropes 6 are turned twice in sequence through the guide assembly. The first turn turns the two first traction ropes 6 from the direction along the mop rod 1 to the direction along the two ends of the cross bar 8. The second turn further turns the two first traction ropes 6 to the middle direction of the cross bar 8, and finally fixes the opposite sides of the two cleaning components.

[0040] Since the mop in this embodiment is provided with a traction rope and a unique guide assembly for squeezing water, the combined application of the cleaning component rotating to clean the floor and the cleaning component back-compressing and squeezing water functions in the electric mop can be achieved.

[0041] In a specific embodiment, a through hole is provided at the connection between the mop rod 1 and the mop head, a bearing is provided in the through hole, and the rotating drive rod 5 passes through the bearing.

[0042] Such an arrangement can not only fix the rotating driving rod 5 along the length direction of the mop head to enhance the stability of the mop head, but also reduce the resistance of the rotating driving rod 5 when rotating, thus saving power consumption.

[0043] In a specific embodiment, the steering assembly 4 is a worm gear structure, the transmission shaft 3 is a hard shaft, and the end of the hard shaft away from the motor 2 is fixedly connected to the worm 101 in the worm gear structure, and the worm wheel 102 in the worm gear structure is fixedly connected to the rotating drive rod 5.

[0044] When the electric mop starts working, the control switch is turned on to provide power to the motor 2, and the output end of the motor 2 starts to rotate, driving the hard shaft connected to it and the worm 101 fixedly connected to the hard shaft to rotate, and the worm 101 is connected to the worm wheel 102 fixedly connected to the rotating drive rod 5, thereby driving the rotating drive rod 5 to rotate.

[0045] It should be noted that, although in the present specific embodiment, the steering assembly 4 is a worm gear structure, the steering assembly 4 is not limited thereto, and may also be two mutually meshing gears whose axes are perpendicular to each other. Specifically, the gear set may be two helical gears or two bevel gears, one of which is fixedly connected to the transmission shaft 3, and the other is fixedly connected to the rotating drive rod 5.

[0046] It should be noted that the transmission shaft 3 can be a flexible shaft. Compared with the flexible shaft, the setting of a hard shaft can increase the accuracy and stability of power transmission. In order to achieve a better power transmission effect, the hard shaft can be set as short as possible, and the motor 2 connected thereto can be set at a lower position inside the mop rod 1. In order to avoid conflict with the first pulling structure, the first traction rope 6 can be extended along the outer wall of the mop rod 1 and fixedly connected to the first pulling structure.

[0047] Furthermore, the first cleaning assembly 701 includes a first compression plate 1101 close to one end of the mop rod 1, a first limiting plate 1201 close to one end of the rotation driving rod 5, and a first cleaning component 1301 therebetween.

[0048] Specifically, the first cleaning component 701 and the second cleaning component 702 are symmetrical structures along the axis of the mop rod 1. The first pulling structure of the mop rod 1 is pulled out. The two first traction ropes 6 are guided by the guide component and are each fixedly connected to a first compression plate 1101 of a cleaning component. The first compression plate 1101 drives the first cleaning component 1301 to be compressed along the rotating drive rod 5 toward the first limiting plate 1201 of the cleaning component where it is located.

[0049] In a specific embodiment, the rotating drive rod 5 is provided with a strip hole 14 along its axial direction, and the cleaning component is provided with an annular gasket 15 . The inner ring of the annular gasket 15 has a protrusion 16 extending into the strip hole 14 , and the protrusion 16 is slidably connected to the strip hole 14 .

[0050] When the rotary drive rod 5 rotates, the protrusion 16 of the annular gasket 15 stuck in the strip hole 14 drives the annular gasket 15 to rotate. Since the annular gasket 15 is fixedly connected to the cleaning component, the cleaning component is driven to rotate.

[0051] In a specific embodiment, a spring 17 for restoring the compressed cleaning assembly to its original state is provided along the axial direction of the rotating drive rod 5 , and the spring 17 is located between the first compression plate 1101 and the first limiting plate 1201 .

[0052] The spring 17 is preferably installed on the rotating drive rod 5, which has the advantages of being light, easy to obtain, and convenient to operate, and can quickly restore the compressed cleaning component to its original state. When the electric mop squeezes water, the cleaning component needs to be squeezed multiple times. The setting of the spring 17 can save the user effort and keep the cleaning component from being deformed for a longer time.

[0053] like Figure 6-7 As shown, a specific embodiment provided also includes two second traction ropes 601, a third steering component and a second pulling structure arranged on the mop rod 1, second limiting plates 1202 are arranged at both ends along the length direction of the mop head, and second cleaning components 1302 are arranged at both ends in the width direction. The two second cleaning components 1302 are respectively provided with guide rods 18 along the length direction of the mop head. Both ends of the two second cleaning components 1302 can be detachably connected to the two second limiting plates 1202, and second compression plates 1102 are respectively arranged between the second limiting plates on the same side thereof. Each of the compression plates is slidably connected to the two guide rods 18, and the two second traction ropes 601 are located outside the second cleaning component 1302, one end of which is fixedly connected to one of the two second compression plates 1102, and the other end is fixedly connected to the second pulling structure. The connection between the mop head and the mop rod 1 is provided with the third steering component for changing the extension direction of the two second traction ropes 601. When the two second traction ropes 601 are pulled, the two second compression plates 1102 drive the second cleaning component 1302 to compress toward each other along the length direction of the mop head.

[0054] It should be noted that the third steering component may be a steering column, a steering elbow, or a bearing.

[0055] During use, when the cleaning component needs to squeeze water, the second pulling rope 601 is pulled through the second pulling structure, and the second pulling rope 601 redirects the force along the axial direction of the mop rod 1 to along the length direction of the mop head through the steering component. The two second compression plates 1102, under the tension of the second pulling rope 601 fixedly connected thereto, drive the cleaning components to be compressed toward each other along the length direction of the mop head to complete the squeezing of water from the mop.

[0056] Since the electric mop of this embodiment is designed with two cleaning components arranged inside the mop head, two second traction ropes 601 arranged outside the cleaning components, and a second compression plate 1102 structure detachable from the cleaning components, the combined application of the cleaning components rotating to clean the floor and the cleaning components compressing and squeezing water towards each other in the electric mop can be realized.
